The Paris Agreement invites signatory countries to formulate and communicate long-term low greenhouse gas emission development strategies (LT-LEDS). This report compares the experience of three developed countries that have communicated LT-LEDS within the framework of the United Nations...

Developing Asia has the world's fastest greenhouse gas emissions growth. This study uses an economy-energy-climate model to assess the effects of Paris Agreement pledges on Asia, in comparison with business as usual (BAU) and more ambitious scenarios. Results confirm that pledges must be...

This paper studies the long-term distribution of energy-efficiency outcomes in the German residential sector. To uncover the underlying energy efficiency of buildings, we estimate the causal response of building-level heat energy demand to variability in heating degree days. We examine...

This paper uses a global integrated assessment model to assess how developing Asia, the world's fastest-growing source of carbon emissions, could transition to low-carbon growth. It finds that national net-zero pledges do not have a high chance of keeping peak warming below 2°C. Under an...

CO2 emissions from international shipping, which are currently unregulated, are predicted to rise from 2.7% today to 18% in 2050. International bunker fuel emissions have been excluded from any commitment in the Kyoto Protocol; the UNFCCC conference in Copenhagen also failed to bring about clear...

This paper provides decision-makers with a framework for prioritising different economic, social and environmental goals and analysing the options available to achieve them. To this end, it develops three stylised COVID-19 recovery pathways (“Rebound”, “Decoupling” and “Wider...

As reporting GHG emissions becomes mandatory in the financial sector, the methods by which emissions are calculated will grow in importance for their impact on the resulting metric. Progress is underway in both the public and private financial sectors to embed emissions accounting standards, but...

Countries have pledged to stabilize global warming at a 1.5 to 2°C increase. Either target requires reaching net zero emissions before the end of the century, which implies a major transformation of the economic system. This paper reviews the literature on how policymakers can design climate...

Copenhagen Consensus Center organized an initiative, in which an Expert Panel of outstanding economists convened in Washington DC in September 2009 to compile a prioritized list of specific solutions in the fight against Climate Change. The basis for the discussions and the ranking were...
